Looks about the same as spinning by beer in my freezers ice tray for about 20 seconds. I would love to know how long you have to wait until the can of beer won't explode.

According to that website, because they form a "Rankine vortex" in the beverage itself, the carbonation is not disturbed. Not sure I buy that, but that's their sales pitch.

a 'Rankine vortex' is a fancy name for a very simple theoretical model.

It's just a circular vortex in which u~1/r and there may or may not be a solid body core. A lot of spinny vortices are like this.

I'm not sure where they think their rankine vortex is - whether in the bottle or round the outside - or whether they are accounting for friction when calling it that.
